1. To help your child to understand the concept of multiplication in a visual and sensorial way:

- Multiplication (乘法) is adding the same number over and over again (乘法是一次又一次地添加相同的数量。)
- Multiplicand (被乘数[bèi chéng shù]) is the number that gets multiplied
- Multiplier (乘数 [chéng shù]) is the number that you are multiplying by.

He was able to understand the concept and he said the number of twos gives...Updates 26 May 2016 (7Y2M21D)Since I returned back to full time work for the last 4 months, Montessori has taken a backseat. Today, he has no play date. My mum picked him up earlier at 3pm, so that we could do Montessori, before he went off for his music class. Thankfully, our baby was sleeping, so that we could have uninterrupted time. He chose to first write the 2 time-table by pencil. He could do it completely. Then I asked him to construct it with beads to make sure that he understood the concept. I asked him to say, 2 x 2 means 2 taken 2 times in mandarin... he wasn't so keen to say it. I also ask him to count that there are 9 bars in 2 x 9. We also did skip-counting... 2, 4, 6, 8, 10, 12, 14... etc. so that he understood the concept of time table. I randomly asked him the 2 time-table, that was a little more challenging.
